Woy Woy Landfill Gas Abatement Facility

Woy Woy Landfill Gas Abatement Facility is a landfill gas abatement project located at the Woy Woy Waste Management Facility on Nagari Road, approximately 10km south of Gosford on the New South Wales Central Coast. Registered in August 2013, the project operates within a 50-hectare waste management site surrounded by the residential suburbs of the Woy Woy Peninsula and the natural bushland of the Brisbane Water National Park.

Electricity generation from landfill gas projects involves installing a gas collection system to capture methane emissions, a potent greenhouse gas, produced by decomposing putrescible waste. The captured methane is then combusted either via flaring or used to generate renewable electricity, preventing it from entering the atmosphere and reducing the site's overall greenhouse gas footprint.

The Woy Woy Peninsula and broader Central Coast region experience a temperate coastal climate with a moderate to high average annual rainfall of around 967 mm. The local area is characterized by flat, highly permeable coastal sandy soils, giving way to sandstone and clay in the surrounding elevated terrain. The primary land use in the immediate vicinity includes urban residential development, coastal recreation, conservation bushland, and municipal waste management.

This project captures and combusts gas generated at the Woy Woy landfill from both legacy and non-legacy waste. It is notable for having transitioned through several methodology variations, moving from a revoked 2012 Carbon Farming Initiative method to the 2015 Landfill Gas method, and most recently adopting the 2021 Electricity Generation from Landfill Gas determination. Additionally, the project successfully completed a fixed delivery carbon abatement contract (CAC210760) in June 2022, which saw 130,000 Australian Carbon Credit Units (ACCUs) delivered to the Commonwealth. In late 2023, the project proponent changed from AGL Energy Services Pty Ltd to LMS Energy Pty Ltd, an experienced renewable energy developer that operates the site's gas extraction and generation infrastructure.
